    The protein

    Catalyzed reaction/ biological activity

  • processing of pro-sigma-K to active [protein|24F7FD5C7C3A68BB2760ABB8CBD8FBD65E5FF7D4|SigK] [Pubmed|19805276]

    • Protein family

  • peptidase M50B family (according to Swiss-Prot)

    • [SW|Domains]

  • C-terminal cystathionine-beta-synthase (CBS) domain, this domain binds ATP [Pubmed|19805276]

    • Effectors of protein activity

  • ATP regulates substrate access to the active site and renders cleavage sensitive to the cellular energy level [Pubmed|19805276]

    • [SW|Localization]

  • integral membrane protein [Pubmed|11959848]
